Dynamic Friction Company True Balanced Brake DRUM (1) 365-80005 For 1981-1983 Mazda GLC, 1982-1985 Mazda RX-7

All DFC Brake Drums are machined to the tightest tolerances in our state-of-the-art facilities to ensure proper fitment and smooth operation, from the very first stop. Unlike other manufacturers who machine and balance drums on the same lines as rotors, DFC utilize dedicated vertical turning centers and balancing machines to manufacture our brake drums. This ensures that each brake drum is correctly machined and electronically balanced to further eliminate vibrations and guarantee a true fitment. Lastly, every DFC brake drum passes a 100% inspection station that critical attributes to ensure proper form, fit, and function.
